The present invention is a heater or heating device that uses microwave energy to generate heat quickly. The heater generates heat quickly by forcing air over microwave-heated oil or non-freeze liquid. As a non-limiting embodiment, the heater preferably includes most or all of the following components: an outer casing or housing, at least one air intake vent, a magnetron, a microwave emitter, a wave scatterer, at least one fluid holder, fluid, a capacitor, a transformer, a microwave containment casing, and a perforated microwave guard. As another non-limiting embodiment, the heater preferably includes most or all of following components: an outer casing or housing, a cooling fan, a magnetron, a microwave emitter, a wave scatterer, at least one non-freeze liquid holder, non-freeze liquid, a capacitor, a transformer, a microwave containment casing, a glass tube, a metal tube, a fan coil, a pump, a reservoir and expansion tank, and a fill plug.

Embodiments of the disclosure include processes using microwave heating to promote the separation of components of crude oil. In some embodiments, microwave-heated water may be used to heat the interphase between the gas phase and the oil phase of a crude oil stream to promote the separation of sulfur (for example, H.sub.2S) and light end components of the crude oil stream. In some embodiments, microwave-heated water may be used to heat the interphase between the oil phase and the water phase of a crude oil stream to promote the separation of water, salt, or both of the crude oil stream. Systems having a microwave unit to provide microwave-heated water to crude oil stream are also provided.

A water heater and a method of heating water utilizing microwave energy are disclosed. The water heater includes an inlet pipe connecting tubular coils. The tubular coils overlap over one another in a pyramid-shape structure. The tubular coils include a microwave generator positioned adjacent to them. The water heater includes an insulation member that positions around the tubular coils. The tubular coils connect to an outlet pipe including a pressure relief valve and a switch. The inlet pipe supplies cold water to the tubular coils. The microwave generator produces microwave energy directed at the tubular coils. The microwave energy penetrates into the tubular coils and heats up the water. The insulation member reflects back the microwave energy into the tubular coils and ensures there is no loss of energy. The hot water flows through the outlet pipe.

A microwave heating apparatus is provided herein comprising a tubing conduit consisting of two or more removable bend portions connected to each other. The tubing conduit is supported by a support system. Each removable bend portion includes a microwave emitter to heat a fluid flowing through the conduit. The apparatus can replace or be integrated into existing heating equipment used in, for example, steam cracking of hydrocarbons. Also provided are pipe segments, such as spools, that are adapted for heating a fluid by applying microwave energy. The pipe segments can be lined with microwave absorbing materials and comprise an opening through which an insert comprising a microwave emitter can be removably inserted and retained.

A solid-state radio frequency (SSRF) water heating apparatus is disclosed. In embodiments, the SSRF water heater includes a water tank, SSRF generator array and RF sensors enclosed within an RF-shielded cage. The SSRF array synthesizes RF signals in the microwave range and transmits the RF energy through the water tank, exciting and heating the water molecules without direct contact. The RF sensors at the opposite end of the tank sense residual RF energy not absorbed by the water. Control processors regulate the generation and transmission of the RF energy based on the sensed residual energy. The heated water and/or generated steam is piped to hot water dispensers, beverage makers, or steam ovens.

A water heater appliance, including methods of operation, is provided herein. The water heater appliance may include a casing, a tank, an inlet conduit, an electric heating system, and a controller coupled to an auxiliary power generator. The tank may be disposed within the casing and define an inlet and an outlet. The inlet conduit may be mounted to the tank at the inlet of the tank. The controller may be operably coupled to the electric heating system and configured to initiate a heating cycle. The heating cycle may include identifying a daily peak auxiliary power period, determining a contemporary voltage reading at the water heater appliance, predicting an occurrence of the daily peak auxiliary power period from the auxiliary power generator, and heating water within the water heater at the predicted occurrence of the daily peak auxiliary power period.

The claimed invention provides an eco-friendly alternative to traditional gas boilers, specifically the claimed invention provides a boiler that uses microwaves as a means to heat water within a boiler system. Preferably the water enters the boiler via one or more spray nozzles to produce a plurality of droplets or mist, which is then heated when they are exposed to the generated microwaves within the boiler.
